ssGetDataTypeSize

Get the size of a custom data type

Syntax

int_T ssGetDataTypeSize(SimStruct *S, DTypeId id)

Arguments

S

SimStruct representing an S-Function block.

id

ID of a data type.

Returns

An int_T value indicating the size of the data type specified by id, if id is valid and the data type's size has been set. Otherwise, returns INVALID_DTYPE_SIZE and reports an error.

Description

Use to obtain the size of a custom data type.

Note

Because this macro reports any error that occurs when it is invoked, you do not need to use ssSetErrorStatus to report the error.

For more information about using custom data types in S-functions, see Configure Custom Data Types.

Languages

C, C++

Example

The following example gets the size of the int16 data type.

int_T size = ssGetDataTypeSize(S, SS_INT16);
if(size == INVALID_DTYPE_SIZE) return;
